The Relationship between Stock Risk and Return Using the Consumption Based Capital Asset Pricing Model (C-CAPM) in the Food and Pharmaceutical Industries

Capital Market and securities exchange has an important role in economic growth, and one of the most important theories and models for these markets, is the consumption-based capital asset pricing model (C-CAPM). This model is a tool to explain the relationship between risk and return of assets in the stock market. Our results show that in the food industry, consumption index in both the consumer price index and import index have no impact on the systematic beta estimation, but the systematic beta have the expected sign and is significant. In the pharmaceutical industry and in the model containing the consumer price index variable, the both estimated betas are not significant, but in the model containing the growth rate of imports variable in food industry, the consumption beta is significant and the systematic beta is not significant.
